Great for bored dogs
Color: Flip Board, Size: Level 2
Great dog puzzle! My pup loves this, he did chew the peg portion once he got them out so they can be put back in. They are tough for small dogs to get out so I think he plotted it out.

My dog is beside herself with glee
Color: Blue
This was a good find. My Lab has a soft mouth so she won’t destroy it, not sure how it would hold up for our neighbor’s German Shepherd with his strong jaws and big teeth.

Is not indestructible
Color: Blue
You have to limit the amount of time your pet plays with this or it will be broken the first time they play with it. Mine got broke (one side ripped off) on the 3rd time he played with it. He loves playing with it.

Very good
Color: Blue
Tried this ball with a friend’s dog. It moves in fun ways and holds the pet’s focus for ages. Tough material resists bites really well.

Not for big, brave dogs.
Color: Blue
So maybe if you have a little dog, or a timid dog, this could be good. However, my 7 month golden just grabs it and carries it with her head shaking and then wants to chew it. So while it’s kinda funny, and she does love it, I just have to walk around trying to keep her from chewing it up. It is as advertised and seems pretty sturdy. It is soft enough to gently throw but is very easily retrieved and then the shaking and chasing continues. Not what I expected.
